Available in PDF, EPUB and Kindle. Book excerpt: The rotating detonation wave engine feasibility program is reported. The theoretical studies included the study of the structure of a detonation wave through a two-phase medium has continued emphasizing the droplet shattering mechanism. Utilizing a theoretical relation for a shear-type breakup developed by Dodd, it is concluded that the distance predicted for droplet breakup behind the strong normal shock wave associated with an H2-O2 detonation can be much smaller than experimentally observed distances between the shock and the zone of significant chemical reaction. It is concluded therefore that the droplet shattering effect occurring behind the shock wave can be of extreme importance in substaining a Chapman-Jouguet detonation in dilute sprays. Also reported is the study of the heat transfer to the wall of a rotating detonation wave engine. And the study of an analytical model for the gas dynamics associated with the rotating detonation wave engine.

Download or read book On Liquid Rotating Detonation Rocket Engine Characterization and Performance written by Vidhan Malik and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The current research investigates a next-generation method of combustion called detonations for propulsive applications which has support from the Combustion Services Branch at the Air Force Research Laboratory (AFRL) of the Rocket Propulsion Division. The overall initiative seeks to explore the viability of detonation-based systems to augment or replace current rocket propulsion methods in the coming five years. The present work progresses this vision by providing proof of a liquid RP-2 based Rotating Detonation Rocket Engine (RDRE) as well as the fundamentals associated with the physics involved to further the understanding of the phenomenon and its potential uses. Phase one of the research starts with development of a theoretical model based on the Zel’dovich-Neumann-Doring (ZND) detonation model and the well established D2 droplet burning model to establish a droplet sizing parameter for varying detonation wavespeeds. Phase two then documents the interaction of a millimeter droplet colliding with varying supersonic waves where the goal is to document the breakup and transient evolution of the droplet when imparted with the supersonic flow velocity. Phase three consists of characterization of an unlike-doublet impinging injector using Liquid-RP2 and Air to record the incipient spray behavior relative to varying operating conditions of interest. Phase four comprises of the aforementioned spray interacting with a fully developed detonation wave where Schlieren, CH*, Formaldehyde PLIF and Mie scatter were used to archive the reactions that ensues. Finally, phase five consists of testing a RDRE fueled with liquid RP-2 and O2 as the reactants where thrust measurements and back-end imaging analysis of the wavespeeds provide insight into the operation and sustenance of the combustion phenomenon occurring inside the engine.
Download or read book THE INFLUENCE OF A COMPRESSIBLE BOUNDARY ON THE PROPAGATION OF GASEOUS DETONATIONS written by Eliahou Khedhoory Dabora and published by . This book was released on 1963 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: Theoretical analysis shows that a detonation wave in a gaseous explosive bounded by an inert gaseous medium propagates at a lower velocity than it would have if the explosive were inside a tube with a solid wall. The velocity decrement is found to be dependent primarily on the ratio of the initial densities of the explosive and the inert gases, the reaction length of the explosive and the extent of the explosive normal to the interface. An extension of composition limit criteria shows that there is a limit to the velocity decrement beyond which the detonation is expected to quench and therefore deteriorate into a shock. Extensive experimental results on H2-O2 mixtures bounded by nitrogen and some results on stoichiometric CH4-O2 bounded by different gases show a general agreement with theory. (Author).
